This is probably sacrelige around here. 4.6 3V swap? - Original Pony Car

**BlownFiveLiter** · 10-09-2011, 03:21 PM

Been considering a swap in my 95 that I think I could do fairly easily, and cheaply, too. I've looked around at some prices and I think I could do it pretty cost effectively if I stick with used stuff. The things I'd need for sure are:

1. Engine (obviously). Found as cheaply as $1400 on www.car-part.com
2. 4.6 K-member. Any 96-04 would work, as well as aftermarket
3. Transmission. All the aftermarket options as a 302, but also T-45, or 3650
4. Control pack from FRPP for the 4.6
5. Headers. LRS sells a 2V to 3V header adapter so any 96-04 2V headers will work
6. 4.6 Hydroboost master cylinder

The pluses are that it already makes 315 HP from the factory and that any of the S-197 stuff will bolt right up to the engine, including superchargers, turbos, accessories, can be easily tuned with a handheld SCT/Diablo/Sniper tuner through the OBD II port. The negatives are that even though the engine combo could probably be had fairly cheaply, the go fast parts for it are not. I also believe I would have to come up with an aftermarket fan controller and wire in new fuel pump and WOT relays, since I think the FRPP control pack was meant for a Fox, not SN95. No biggie, but a little extra work to get around the CCRM. I think if I was thrifty enough, I might be able to do it for about as cheap as the parts I'd be selling off the 302 combo (heads, intake, supercharger, injectors, cam, pushrods, rockers, T-5, etc.). We shall see what I do. The thing is just sitting now, so I might as well do something with it!

How did i miss this?

I dont think that it would be sacrilege, its not like your doing a damned LS swap, or even worse an accursed rotary!
Thing is that it would lay down about (im guessing) 50 or so horse less than what you were making with the old setup. you'd get about 270-280 to the wheels with no bolt ons. simple stuff would probably get you to 300 easy, add boost and your over 400 and not having to worry about a busted block. If you can I say DOOOO EEEAATTTTT!
What would be sweet is if you could find a wrecked f150 or mustang with a modular 5.0 and pick that up for the swap...

LSx swap pwns all....

*waits to be shot*

**94gtfreak** · 10-21-2011, 11:09 PM

In all seriousness, a 3V swap would be different from the typical 4V that everyone is doing now. You've got the high rev's of the mod motor as well a large (and continually growing) market for HP goodies.

**BlownFiveLiter** · 10-22-2011, 01:13 PM

And the fact that it's already over 300 HP from a factory engine, before any mods. While I don't believe the 4.6 aftermarket will ever be as large, or inexpensive as the 5.0 Windsor's will be, the fact still remains that it is growing and power can be made with minimal effort. A cam swap on a 4.6 can be done in a probably an hour. Do that on a 302. This is definitely something that will take some time and effort to do the swap while keeping the factory gauges working, but I'm not sure if the end result will have been worth it.

**aar0s** · 10-23-2011, 06:32 PM

run that by me again, you can swap cams in a 4.6 in an hour? hmmm wonder if my wife would notice her car getting lumpy at idle ...

**94gtfreak** · 10-23-2011, 10:12 PM

Matt, if I remember right there was a guy in Germany that did a 3V swap in a 96 V6 but I don't think he kept the factory gauges though. But, where there's a will there's a way!!

If you have the tool that holds the chains in place, yes. It costs $100, but spares you from pulling the front cover off. Of course the cams are $400+!

In all honesty, it'd be about the same as the LRS Fairmont. I'd just need to figure out how to keep the factory gauges working. I think I'd need a 4.6 AC compressor, too. Not totally sure though, since I'm not sure about how it mounts to the 4.6, vs the 5.0.

**94gtfreak** · 10-24-2011, 10:17 PM

Wait...aren't the 05-09 gauges digital input with a manual output?

**BlownFiveLiter** · 10-25-2011, 08:57 AM

I have no idea. I've done exactly zero research about the gauges thus far. Been busy with school and getting ready to go back to work again, since breaking the leg/ankle combo. I went back for one day and my ankle didn't tolerate the activity, so back on leave I went.

**aar0s** · 10-25-2011, 10:20 PM

whats the gains from a set of cams on a 4.6? other than the nasty lumpity lump. I might look into that.

**BlownFiveLiter** · 10-26-2011, 03:49 PM

Same as with any other engine. More duration and lift, so hopefully more power. 4.6 heads (even 2V) outflow probably any 302 factory head ever cast, so the potential to make power is definitely there.

**aar0s** · 10-27-2011, 07:14 PM

did a little looking around and read somethign that reichard racing makes a kit to swap 3v heads on a 2v block but i couldn't find anything on their website. find ya a cheep long block and a wrecked 3v and start wrenching.

**BlownFiveLiter** · 10-28-2011, 05:49 AM

I'd just pick up a complete 3V engine, honestly. They're getting affordable after enough 05+ Mustangs have found their way into junkyards. I think the one I referenced in the first post had low miles, too. Like 30K, if I recall correctly.
